.Application led @ctober 27, 1921. Serial No. 510,904.

To all whom 'it may concern;

Be it known that l, ARTHUR H. blrannnfrr, a citizen of the United States, residing at Athol, in the county of l/Vorcester, Commonwealth of Massachusetts, have invented cer: 'tain new and useful improvements in Steel Rules with Holders, of which the following is a specification.

This invention relates to ruler holders, and particularly to a holder for clamping a relatively short ruler so that the ruler may be laid against surfaces which are inaccessibly located forineasurement, as for example an inside surface.

rlhe object of my invention is to provide a simple and convenient holder which will permit the ruler to be disposed in a variety of positions according to the character of the surface to be measured.

The .construction and operation of my invention is described and illustrated in the accompanying specification and drawings, throughout which lilre reference characters are correspondingly employed, and the characteristic features of novelty are particularly pointed out in the appended claim. ln the drawings: i

liig. 1 is an elevation of a clamp in accordance with my invention.

Fig. 2 is an enlarged view of the handle member, disconnected Fig. 3 is an enlarged view of the holder sleeve, disconnected.

Fig. 4 is an enlarged view of the blade clamp.

Fig. 5 is a longitudinal section'through the sleeve shown in Fig. 3.

Figs. 6, 7, and 8, areviews illustrating the use of the device, and

Fig. 9 is an enlarged section through the assembled device, particularly illustrating the clamping action.

l have indicated at l a handle member which may be milled externally Aas at 2 to provide a convenient gripping surface. Art its forward end the handle l is reduced, as indicated at 3, to provide a stop shoulder and beyond said shoulder extends asa reduced threaded stem portion't adapted to be inserted into a holder sleeve 5 and to engage with a short series of internal threads 6 whereby to detachably connect the handle and sleeve members.

spending to that of the seat 8.

Surrounding' the reduced portion l0 of the plunger is a coil spring l2 which abuts the enlarged head 9 thereof at one end and at its opposite end abuts an internal shoulder l2 on the sleeve 5.

rThe ruler R is adapted to be inserted in the slot and clamped to its seat 8 by the `beveled face ll of the plunger 9 which plunger is pushed forwardly into clamping position by the stem portion Li of the handle l when said handle is threaded into the sleeve 5, The abutment of the shoulder 3 against the rear end of the sleeve 5 limits the forward movement of the handle into the sleeve. The spring l2 is compressed when the plunger@ is moved forwardly by the handle. llhen the handle is unscrewed, the spring expands and moves the plunger 9 rearwardly in the sleeve, relieving the clamping pressure on' the ruler R so that said ruler may be removed from the slot 7.

lThe closed end of the sleeve 5 is beveled, as indicated at i3, preferably at an angle to the seat 8 so that the ruler will be brought up closelyl to the surface to be measured when the beveled end 13 of the sleeve is laid against said surface.

Various modilications in the form and construction of my device may obviously be resorted to all without departing from the spirit of my invention if within the limits of the appended claim.

lhat l therefore claim and desire to secure by Letters Patent is:

A rule holder comprising hollow sleeve having its forward end closed, an inclined seat adjacent its forward end and having a correspondingly inclined slot adjacent said seat and communicating with the hollow in said sleeve and extending from the top of several malgnal edges to releasably clamp the rule against said seat.
